System, Method, and Computer Program Product for Dynamic Passcode Communication

ABSTRACT

Systems, methods, and computer program products for dynamic passcode communication use a merchant application installed on a user device that receives transaction data associated with a transaction at a merchant system. The transaction data may include an account identifier associated with an account at an issuer system. The merchant application determines, based on the account identifier, whether an issuer application associated with the issuer system is installed on the user device. In response to determining that the issuer application is installed on the user device, the merchant application transmits, to the issuer application, a request for a dynamic passcode. The merchant application receives, from the issuer application, the dynamic passcode and transmits, to the issuer system, an authorization request including the account identifier and the dynamic passcode. The merchant application receives, from the issuer system, an authorization response authorizing or denying the transaction.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent application Ser. No. 17/632,556, filed Sep. 1, 2021, which is the United States national phase of International Application No. PCT/US2021/048642 filed Sep. 1, 2021, the entire disclosures of which are hereby incorporated by reference in their entirety.

BACKGROUND 1. Field

This disclosure relates to electronic payment networks and, in some non-limiting embodiments or aspects, to dynamic passcode communication for frictionless multi-factor authentication (MFA) for electronic payments.

2. Technical Considerations

Multi-factor authentication (MFA) (or two-factor authentication) is an electronic authentication method in which a user is authorized only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism (e.g., a user-controlled password with a dynamic passcode or one-time password (OTP), etc.). MFA protects the user from an unknown person trying to access and/or use their data such as personal ID details or financial assets. For example, payment service requirements, such as strong customer authentication (SCA), and/or the like, may require that electronic payments be performed with MFA, to increase the security of the electronic payments. However, the additional factors required by MFA may increase a number of steps that a customer performs to successfully complete a transaction, increase a number of application calls after a transaction is initiated, and/or increase a number of communications between transaction processing systems.

As shown in FIG. 4 , at reference number 402, the merchant application may request and receive a token (e.g., a JSON web token, etc.) from merchant system 102 and, at reference number 404, provide the token associated with merchant system 102 to the merchant SDK. At reference number 406, the merchant SDK may transmit, to payment gateway system 104, the token with the request to register the merchant application with payment gateway system.

As shown in FIG. 3A, at step 304, process 300 includes receiving a confirmation that a merchant application is registered with a payment gateway system. For example, user device 112 may, in response to transmitting the request to register the merchant application installed on user device 112, receive, with the merchant application, from payment gateway system 104, a confirmation that the merchant application is registered with payment gateway system 104. As an example, and as shown in FIG. 4 , at reference number 408, the merchant SDK may receive the confirmation that the merchant application is registered with payment gateway system 104 and, at reference number 410, provide the confirmation to the merchant application.

As shown in FIG. 3A, at step 306, process 300 includes transmitting a request to register an issuer application with an issuer system. For example, user device 112 may transmit, from the issuer application, to issuer system 110, a request to register the issuer application installed on user device 112 with issuer system 110. The request to register the issuer application may include a token associated with each of the account identifier and a device identifier associated with user device 112. The token may be configured to validate the dynamic passcode.

As an example, and as shown in FIG. 4 , at reference number 412, the issuer application may request (e.g., in response to a user logging into the issuer application, etc.) the issuer SDK to initialize registration with issuer system 110 and, in response thereto, at reference number 414, the issuer SDK may transmit, to issuer system 110, the request to register the issuer application installed on user device 112 with issuer system 110. In such an example, the issuer SDK may bind or link a token to user device 112 (e.g., to a device identifier associated with user device 112, etc.), the issuer application installed on user device 112 (e.g., to an application identifier associated with the issuer application, etc.), and/or an account identifier associated with an account that is associated with the installed issuer application and transmit the token with the request to register the issuer application installed on user device 112 with issuer system 110. The token may be stored and/or registered by issuer system 110 in association with the account identifier for use in validating a dynamic passcode generated by the issuer SDK in association with an electronic payment transaction that uses the account identifier.

As shown in FIG. 3A, at step 308, process 300 includes receiving a confirmation that an issuer application is registered with an issuer system. For example, user device 112 may, in response to transmitting the request to register the issuer application installed on user device 112 with issuer system 110, receive, with the issuer application, from issuer system 110, a confirmation that the issuer application is registered with issuer system 110. As an example, and as shown in FIG. 4 , at reference number 416, the merchant SDK may receive, from issuer system 110, the confirmation that the issuer application is registered with issuer system 110.

As shown in FIG. 3A, at step 310, process 300 includes receiving transaction data associated with a transaction. For example, user device 112 may receive, with a merchant application installed on user device 112, transaction data associated with a transaction at merchant system 102. The merchant application may be associated with merchant system 102. The transaction data may include an account identifier (e.g., a PAN, a BIN, etc.) associated with an account at issuer system 110.

As an example, and as shown in FIG. 4 , at reference number 418, the merchant application may receive and/or determine, based on user input from a user to the merchant application, parameters associated with the transaction and, at reference number 420, provide one or more of the parameters (e.g., a BIN, etc.) to the merchant SDK.

In some non-limiting embodiments or aspects, transaction data may include parameters associated with a transaction, such as an account identifier (e.g., a PAN, etc.), a transaction amount, a transaction date and time, a type of products and/or services associated with the transaction, a conversion rate of currency, a type of currency, a merchant type, a merchant name, a merchant location, a merchant, a MCG, a MCC, and/or the like.

As shown in FIG. 3A, at step 312, process 300 includes determining whether an issuer application is installed on a user device. For example, user device 112 may determine, with the merchant application, based on the account identifier, whether an issuer application associated with issuer system 110 is installed on user device 112. As an example, user device 112 may transmit, from the merchant application, to payment gateway system 104, at least a portion of the account identifier, receive, with the merchant application, from payment gateway system 104, an identification of the issuer application associated with issuer system 110 associated with the account identifier, and determine, based on the identification, with the merchant application, whether the issuer application associated with issuer system 110 associated with the account identifier is installed on user device 112.

In such an example, and as shown in FIG. 4 , at reference number 422, the merchant SDK may transmit the BIN to payment gateway system 104 and, at reference number 424, the merchant SDK may receive the identification of the issuer application (e.g., a name of the issuer application, a name of an issuer associated with issuer system 110, etc.) associated with the BIN. At reference number 426, the merchant SDK may scan user device 112 for the identified issuer application and/or verify if the issuer application includes the issuer SDK integrated within the issuer application.

As shown in FIG. 3A, at step 314, process 300 includes transmitting a request for a dynamic passcode. For example, user device 112 may, in response to determining that the issuer application associated with issuer system 110 is installed on user device 112, transmit, from the merchant application, to the issuer application, a request for a dynamic passcode. As an example, and as shown in FIG. 4 , at reference number 428, the merchant SDK may transmit, in response to determining that the issuer application associated with issuer system 110 is installed on user device 112 and includes the issuer SDK, to the issuer SDK, the request for the dynamic passcode. In such an example, the merchant SDK may communicate directly with the issuer SDK.

As shown in FIG. 3B, at step 316, process 300 includes receiving a request for a dynamic passcode. For example, user device 112 may receive, with the issuer application, from the merchant application, the request for the dynamic passcode. As an example, and as shown in FIG. 4 , again at reference number 428, the issuer SDK may receive, from the merchant SDK, the request for the dynamic passcode. In such an example, the request for the dynamic passcode may include the account identifier and/or a device identifier associated with user device 112.

As shown in FIG. 3B, at step 318, process 300 includes generating a dynamic passcode. For example, user device 112 may, in response to receiving the request for the dynamic passcode, generate, with the issuer application, the dynamic passcode. As an example, and as shown in FIG. 4 , at reference number 430, the issuer SDK may generate, based on the account identifier and/or the device identifier, the dynamic passcode. In such an example, the dynamic passcode may be configured for validation with the token registered at issuer system 110 in association with the account identifier.

As shown in FIG. 3B, at step 320, process 300 includes transmitting a dynamic passcode. For example, user device 112 may transmit, from the issuer application, to the merchant application, the dynamic passcode. As an example, and as shown in FIG. 4 , at reference number 432, the issuer SDK may transmit, to the merchant SDK, the dynamic passcode. In such an example, the issuer SDK may communicate directly with the merchant SDK.

As shown in FIG. 3B, at step 322, process 300 includes receiving a dynamic passcode. For example, user device 112 may receive, with the merchant application, from the issuer application, the dynamic passcode. As an example, and as shown in FIG. 4 , again at reference number 432, the merchant SDK may receive, from the issuer SDK, the dynamic passcode.

As shown in FIG. 3B, at step 324, process 300 includes transmitting an authorization request. For example, user device 112 may transmit, from the merchant application, to issuer system 110, an authorization request requesting authorization of the transaction. The authorization request may include the account identifier and the dynamic passcode. In such an example, user device 112 may transmit the authorization request from the merchant application to issuer system 110 via merchant system 102, payment gateway system 104, acquirer system 106, and/or transaction service provider system 108 (e.g., via transaction processing network 101, etc.).

As an example, and as shown in FIG. 4 , at reference number 434, the merchant SDK may bundle and encrypt the dynamic passcode with other authentication parameters and/or transaction parameters (e.g., a username, a password, a pin, a CVV, a PAN, etc.) and, at reference number 436, provide the bundled and encrypted data to the merchant application. At reference number 438, the merchant application may transmit the bundled and encrypted data to merchant system 102 and, at reference number 440, merchant system 102 may transmit the bundled and encrypted data to payment gateway system 104. At reference number 442, payment gateway system 104 may decrypt the data to recover the dynamic passcode and, at reference number 444, transmit the dynamic passcode as part of the authorization request to transaction service provider system 108. At reference number 446, transaction service provider system 108 may transmit risk data associated with a predicted risk of the transaction with the authorization request including the dynamic passcode to issuer system 110. At reference number 448, issuer system 110 may receive the authorization request and determine whether to authorize or deny the transaction based on the risk data and/or the dynamic passcode.

As shown in FIG. 3B, at step 326, process 300 includes receiving an authorization response. For example, user device 112 may receive, with the merchant application, from issuer system 110, an authorization response authorizing or denying the transaction. In such an example, user device 112 may receive the authorization response with the merchant application from issuer system 110 via merchant system 102, payment gateway system 104, acquirer system 106, and/or transaction service provider system 108 (e.g., via transaction processing network 101, etc.).

As an example, and as shown in FIG. 4 , at reference number 450, issuer system 110 may transmit the authorization response to transaction service provider system 108 and, at reference number 452, transaction service provider system 108 may transmit the authorization response to payment gateway system 104. At reference number 454, payment gateway system 104 may transmit the authorization response to merchant system 102 and, at reference number 456, merchant system 102 may transmit the authorization response to the merchant application, which may provide the authorization response including the authorization or denial of the transaction to the user via user device 112.
